CARPET-LINING.

SPECIFICATION forming part of Letters Patent No. 263,531, dated August.29, 1882. Application filed January as, 1882. (No model.)

T all whom it may concern Be it known that I, ll/IARTIN V. Kaonn, of thecity of St. Louis, in the State of Missouri, have invented a certain newand useful Carpet- Lining, of which the following is a specification,reference being bad to the accompanying drawings, forming part of thesame.

The object of my invention is to provide a new carpet-lining that willpresent a smooth surface to the carpet, thus avoiding wear, will allowthe escape of dust through it, thus preventing wear and dirt, and willat the same time form a cushion beneath the carpet. The article can beproduced at so low a price as to be within the reach of all users ofcarpets.

It consists of thick paper or straw board having numerous perforationsmade with a blunt instrument, or one that will not cut away any of thematerial, the material being forced outward at the bottom of theperforations form- I ing annular cushions or lips extending beneath thebody of the sheet.

Figure l is a top view, showing portions of the floor, lining, andcarpet. Fig. 2 is an enlarged top view of a piece of lining, and Fig. 3is a bottom view of same. Fig. 4 is an enlarged sectional view of thelining.

'ihe lining is formed of thick paper or. straw board, made in sheetsB,or rolls of any suitable size. The sheet has numerous perforations,I), which are made with an instrument that does not cut away any of thematerial, but

which, in making the perforations, forces the material downward andoutward around the lower end of the holes I), beneath the body of thesheet, in an annular cushion, c, in which the fibers of the board arecrowded into a confused mass, which forms a permanent cushion. The topof the sheet B remains so unruffled and smooth that it will not wear thecarpet. In this it differs from cloth linings, in which the threads wearthe carpet by abrasion. The dust descending through the carpet I) to thelining will escape through the holes I), thus keeping the carpet cleanand avoiding wear from grit. The perforations will not be liable tobecome closed by the pressure of the annular cushions 0 against thefloor A, because the circular form of the perforation enables it toresist collapsing strain against its sides.

I have made the lining by running it between two matching-rollers, oneof them studded with points to make the perforations and the other onepitted with indentations for the reception of the points and cushions c.

I claim- As an improved article of manufacture, carpet-lining formed ofpaper-board, with numerous perforations, b, and annular cushions c,substantially as set forth.
